Argweld® Weld Backing Tape

The tape would ideally be used for

One-sided welding of weldable metal.
To achieve a flatter, smooth, coke free weld bead to minimise the need for post-weld grinding and cleaning.

Common metals welded with 'Backing Tape' include

carbon steels

stainless steel

chrome-moly and duplex steels

copper nickel

cast iron

The tape comprises a 75 mm wide, heat resistant aluminium sticky tape, in the centre of which is a 25 mm wide band of woven glass fibre cloth.

The material is available in two grades

Light duty for use up to 80 amps

Heavy duty for use up to 160 amps

It is possible to weld onto the tape with MIG, Stick, TIG or plasma processes, so long as the recommended current levels are not exceeded.

The lightweight grade comes in 25 metre lengths and the heavyweight in 12.5 metre lengths.

If lengths are needed to be joined, rolls of the sticky aluminium tape without the fibre are available from Huntingdon Fusion Techniques Limited, allowing a small length to be cut off to join two lengths of the 'Backing Tape' together.
